The usually prolific Ronaldo was off target with a 53rd-minute penalty, awarded after a video-assisted review, as Portugal failed to build on Ricardo Quaresma's first-half stunner in the crucial Group B contest.

That miss from Ronaldo, who was perhaps fortunate not to see red for another VAR check after swinging an arm into the face of Morteza Pouraliganji, was punished when Cedric Soares was pinged for handball after referee Enrique Caceres again went to his video monitor.

The 32-year-old netted the only goal of the game to help the European champions to victory in Moscow, beating goalkeeper Igor Akinfeev from close range early on.

As man of the match, he was due to appear in front of the press, but Ronaldo was in no mood to take any questions amid ongoing uncertainty about his future at Madrid and stuck to a few prepared words on Portugal's win.

"Obviously we are very happy, it is the first time that Portugal wins in Russia," he stated.
